When creating a project from the seam-ear-archetype (see http://code.google.com/p/open-archetypes/wiki/seamEarArchetype),
the Seam Maven configurator doesn't install the seam facet on any project.

I'm prepping for staging m2eclipse-wtp 0.12, so I don't know if this is a regression or not.

The JBoss Maven facet is correctly installed, the Seam configurator appears on the lifecycle mapping page.
